This is suppose to be solved using the multiplication principle. If possible please show me not just the answer but how you came up with it so I understand how to do these problems. Thank you

multiply both sides by 144 (which is 9 x 16)
(144)(x/9)=(144)(1/16)
16(x) = 9(1)
16x = 9
x = /9/16
you could just 'crossmultiply' to get the same result faster:
(x)(16) = 1(9)
x = 9/16
In general find the lowest common denominator of your fractions, and multiply each term by that.
This will guarantee that all your denominators will cancel, and your fractions will disappear.
